Swing training device

ABSTRACT

A swing training apparatus includes an upper line from an upper assembly to a housing of a lower assembly. A first line extendable from the housing may be connected to a sporting implement. A second line extendable from the housing may be connected to the upper line. A first spool, second spool, lever, and pawl are located within the housing. The rotation of the first spool permits the extension of the first line. The pawl is biased to prevent the rotation of the first spool. Tension in the second line cause the rotation of the second spool, causing the lever to engage a portion on the pawl to disengage the pawl and permit extension of the first line. The first and second spools, lever, and pawl are configured to permit the extension of the first line at the proper “release” point during the swing of a sporting implement.

BACKGROUND Field of the Disclosure

The embodiments described herein relate to a swing training device that teaches a user the proper “release” point during a swing. The swing training device may be used to train a user the proper “release” point during a swing for various sports, such as, but not limited to golf, baseball, and softball.

Description of the Related Art

Baseball and softball are popular sports. One aspect of becoming a good baseball or softball player is perfecting the swing to “release” the wrists at the proper point during the swing to provide maximum force to the ball. Learning this technique can be rather difficult and may frustrate players learning the sport. A need exists to provide an apparatus that aids in teaching the proper “release” point during a swing.

Golf is also a popular sport, but one obstacle in becoming a proficient golfer is mastering a consistent golf swing. Over the years there have been many advancements in golf club and golf ball technology that help a golfer to hit golf balls in a straight or intended direction. However, a golfer who lacks a proper, consistent golf swing may not perform up to internal expectations even with these technological advancements, which may lead to disappointment, frustration, and even the possibility that the golfer may give up on the game of golf.

An improper golf swing is prevalent among golfers, young and old, beginners and veterans. One possible difficulty in learning the proper swing is that often it is hard to translate theory into practice. Even the smallest incorrect movement during golf swing can be crucial. One critical movement in a golf swing is “releasing” the wrists at the correct time. Golfers, both beginners and veterans, may not even realize that they are “releasing” their wrists too early or too late in their swing. A golf professional may recognize such a mistake in a golfer's swing, but correcting the problem may not be easy as it is difficult to teach the exact point during the swing that the wrists should be “released.”

One key to hitting a golf ball is developing a golf swing that permits the club to strike the golf ball with the greatest generated force, but so that the club hits the ball as “squarely” as possible. This requires the golfer to perform the entire swing correctly. During a swing, it is important to keep the trailing wrist bent during the swing until the point where the club head is within approximately 18 inches away from the ball. At that point, the wrists should “release” and the trailing arm should start to straighten out thereby creating a “sling-shot” effect. The timing of the wrist “release” not only affects the impact force, it also affects the accuracy. Accordingly, there is a need for a training device and method of training to assist a golfer in the development of proper swing technique and “wrist and arm release” to achieve a consistently repeatable and effective golf swing.

U.S. Pat. No. 6,863,616 to Snyder et al. (“Snyder”), which is incorporated by reference herein in its entirety, recognized this problem and discloses a device intended to train a golfer to learn the proper point in a swing to “release” the wrists. Snyder discloses a training device that uses a trigger line to release a ratchet wheel, which is connected to a ratchet line that is connected to a golf club. The device of Snyder is intended to “release” the ratchet at the proper time during the correct swing. The device of Snyder has some deficiencies. A device training a golfer the proper release point needs to provide a consistent mechanism that has same repeatable release point. The trigger line of Snyder is attached to the ratchet mechanism, locking and releasing the ratchet line. Both of these lines apply opposing forces to the ratchet wheel of Snyder. As the ratchet wheel returns to the initial position after a swing the “pull” of the trigger line varies to release the ratchet wheel, which in turn varies the “release” point on subsequent swings. Therefore, Snyder does not always provide a consistent “release” point. An improved training device is desirable.

Additional disadvantages of Snyder and other current training devices may exist.

The knob 121 may be configured so that the user can lift the knob 121 and turn to locate the pointer 129 for reference to the initial position of the chain 111. The length of chain 111 determines the release point during the swing as discussed herein. The pointer 129 may be used by reference for the user in regards to adjustments to the length of chain 111 to designate various skill levels of the user. Alternatively, the second line 134 (shown in FIG. 1) of the lower assembly 130 may be connected directly to the adjusting unit 120 as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure. In other words, the second line 134 and the upper line 111 may be integrated into a single line.

FIG. 4 shows an embodiment of a lower assembly 130. The lower assembly 130 includes a connector configured to selectively connect the lower assembly 130 to the forearm of a user. The connector may be two adjustable straps 136,137 as shown in FIG. 4. The size of the straps 136, 137 may be adjusted via buckles 139, 140. Various other connectors may be used to selectively connect the lower assembly 130 to the forearm of a user as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure. A first line 133 is extendable from a first end of the housing of the lower assembly 130. The housing may be comprised of an upper housing 131 connected to a lower housing 132, collectively referred to herein as the housing. The housing may comprise other configurations as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure. The end 135 of the first line 133 may include a loop 171 that is configured to connect to a clip 138 (shown in FIG. 1) that may be selectively attached to a shaft of a sporting implement, such as a golf club or a bat. A second line 134 is extendable from a second end of the housing and the end of the second line 134 includes a connector 160. The connector 160 may be connected to a first end of the upper line 111 (shown in FIG. 2) from the upper assembly 110 via a connector 112 as discussed herein.

FIG. 5 shows an exploded view of the housing comprised of upper housing 131, lower housing 132, and base 141, collectively referred to as the housing, of the lower assembly 130. The straps 136, 137 of the lower assembly 130 may be secured between the lower housing 132 and the base 141. The base 141 may be removed from the lower housing 132 to permit the replacement of the straps 136, 137 with different straps. Positioned within the housing is a first spool 143 that includes teeth 144 on at least a portion of the exterior of the spool 143. A spring 145 spring loads the first spool 143 and biases the first spool 143 to an initial position. A first line 133 is spooled around the first spool 143. The housing includes a bushing 146 to aid in aligning the first line 133 it passes through a grommet 142 to exit the housing. The end 135 of the first line 133 may be formed in a loop 171 that is configured to connect to a clip 138 (shown in FIG. 1) via a connector 170 and a bumper 172 is positioned adjacent to the end 135 of the first 133 to protect the lower assembly 130, as discussed herein.

Positioned within the housing is a second spool 147 that includes teeth 148 on at least a portion of the exterior and a spring 149 that spring loads the second spool 147 and biases to an initial position. A second line 134 is spooled around the second spool 147. The second line 134 extends out of the housing and includes a connector 160 on the end of the second line 134. A pawl 150 is positioned within the housing and spring 152 biases the pawl 150 into engagement with the teeth 144 of the first spool 143 to selectively prevent rotation of the first spool 143 and extension of the first line 133. Positioned within the housing is a lever 155 that is positioned adjacent to the pawl 150. The lever 155 is configured to selectively engage the second spool 147 and the spring 156 biases the lever 155 to engagement with the teeth 148 of the second spool 147. Rotation of the second spool 147 in one direction may engage lever 155 and the lever 155 may “slip” over the teeth 148 when the second spool 147 rotates in the opposite direction. The lever 155 is configured to selectively engage a portion of the pawl 150 as discussed herein. Spring 156 biases the lever 155 to an initial position in which the lever 155 will engage or ratchet teeth 148 of second spool 147. Various configurations of the pawl 150 and lever 155 may exists so that movement by the lever 155 may engage a portion of the pawl 150. For example, the pawl 150 may include a pin, teeth, or projection 151 that the lever 155 selectively engages as illustrated in FIG. 5. The lever 155 is selectively pivoted by the second spool 147 to engage the projection 151 to pivot the pawl 150 away from the first spool 143 to selectively permit the rotation of the first spool 143 and extension of the first line 133 as disclosed herein.

FIGS. 6-8 shows top views of the inside of the housing with the upper housing 131 removed for illustrated purposes. When using the swing training device, the upper assembly 110 and lower assembly 120 will be positioned on a user's upper arm and forearm respectively. The second line 134 will be connected to the upper line 111 and with the arm in a substantially straight position the user will be able to extend the first line 133 as there is tension on the second line 134 and connect the first line 133 to a shaft of an implement, such as a golf club via connector 170 and clip 138 as shown in FIG. 9. The tension in the second line 134 rotates the second spool 147 in a clockwise direction. As the second spool 147 rotates in a clockwise direction the teeth 148 of the second spool 147 engage the lever 155 which pivots away from the first spool 143 about pivot point 165 and engages the projection 151 of the pawl 150. As the lever 155 continues to pivot away from the first spool it will cause the pawl 150 to also pivot away from the first spool 143 about pivot point 165 via engagement with the projection 151. The pivoting of the pawl 150 disengages the pawl 150 from the teeth 144 of the first spool 143 permitting the first spool 143 to rotate in a counter clockwise direction (indicated by arrow A). The first line 133 may then be extended outward (indicated by arrow B) so that it may be attached to a shaft of a sporting implement.

FIG. 6 illustrates the components within the housing in an initial configuration after first line 133 has been connected to the shaft of a sporting implement as the user starts a back swing. During the back swing, the user bends his or her elbow causing the second line 134 be retracted into the housing (indicated by arrow C) by the counter clockwise rotation of the second spool 147 (indicated by arrow D). The lever 155 ratchets as the second spool 147 rotates in a counter clockwise direction and the pawl 150 remains engaged with the teeth 144 of the first spool 143 selectively preventing the rotation of the first spool 143 in a counter clockwise rotation. In addition, the first spool 143 is free to run in the clockwise direction as the user's wrist is angled.

FIG. 7 illustrates the components within the housing at the start of the downward swing of a sporting implement, such as a golf club. During the downward swing, the elbow of the user's arm opens up, which pulls on the second line 134 (indicated by arrow E) that is connected to the upper line 111 of the upper assembly 110. The tension on the second line 134 causes the second spool 147 to rotate in a clockwise direction (indicated by arrow F). The teeth 148 on the second spool 147 are configured to cause the lever 155 to ratchet when rotating in the counter clockwise direction, but are configured to engage the lever 155 when rotating in the clockwise direction. The engagement of the teeth 148 with the lever 155 pivots the lever 155 away from the first spool 143 about the pivot point 165 (indicated by arrow G). As the lever 155 first begins to pivot away from the first spool 143, the pawl 150 remains engaged with the teeth 144 of the first spool 143 preventing the first spool 143 from rotating counter clockwise, which prevents the first line 133 from extending out of the housing. This prevents the user from “releasing” his or her wrists during the downward swing too early.

FIG. 8 illustrates the components within the housing at the point of the downward swing of a sporting implement, such as a golf club, that the user should “release” his or her wrists. At the proper point during the downward swing, the lever 155 engages the projection 151 of the pawl 150 and the pawl 150 and lever 155 pivot together away from the first spool 140 (indicated by arrow H), which disengages the pawl 150 from the teeth 144 of the first spool 143. With the pawl 150 disengaged, the first spool 143 is free to rotate in a counter clockwise direction (indicated by arrow I), which permits the first line 133 to unspool off the first spool 143 extend out of the housing (indicated by arrow J). The selective releasing of the first spool 143 will provide the user with the proper point along the downward swing to “release” his or her wrists. A proper swing by the user will result in the clip 138 remaining on the shaft of the sporting implement, which may be a golf club or bat. An improper swing will result in the clip 138 to “pop off” of the shaft of the implement being swung. The “pop off” provides both a physical and audible indication to the user concerning the improper swing. The adjustment unit 120 of the upper assembly 110, as described herein, permits the “release” point to be turned to allow a higher level of skill to be obtained by the user. The interaction of the pawl 150, lever 155, and second spool 147 permit the apparatus 100 to “release” accurately at the proper point during repeated swings.

FIG. 9 shows the swing training apparatus 100 in conjunction with a golf club positioned on a user's arm. The upper assembly 110 is positioned on the upper portion of the arm and the lower assembly 130 is positioned on the forearm portion of the arm. The first line 133 of the swing training apparatus 100 is connected to the shaft of a golf club via a clip 138. A connector 170 connects a loop 171 at the end of the first line 133 to the clip 138. The adjustment unit 120 may be used to lengthen or shorten the upper line 111 to make fine adjustments to the “release” point during a downward swing of a golf club.

FIG. 10 shows the swing training apparatus 100 in conjunction with a baseball or softball bat positioned on a user's arm with the upper assembly 110 positioned on the upper portion of the arm and the lower assembly 130 positioned on the forearm portion of the arm. The first line 133 of the swing training apparatus 100 is connected to a baseball bat via a ring or doughnut 210 and clip 220. The doughnut 210 may be slid over the end and down the bat until tight on the shaft of the bat. Clip 220 may then be secured around the doughnut 210. A connector 170 connects a loop 171 at the end of the first line 133 to the clip 220. As discussed herein, the adjustment unit 120 may be used to lengthen or shorten the upper line 111 to make fine adjustments to the “release” point during a swing of the bat.
